Compile errors on OSX 10.13.6: undeclared identifier 'EROFS'

[weaver299]

I'm attempting to compile on MacOS 10.13.6 and getting these errors:

In file included from jmtpfs.cpp:23:
./mtpFilesystemErrors.h:94:47: error: use of undeclared identifier 'EROFS'
        ReadOnly() : MtpFilesystemErrorWithErrorCode(EROFS, "read only") {}
                                                     ^
./mtpFilesystemErrors.h:100:59: error: use of undeclared identifier 'ENOTEMPTY'
        MtpDirectoryNotEmpty() : MtpFilesystemErrorWithErrorCode(ENOTEMPTY, "Directoy not empty") {};
                                                                 ^
./mtpFilesystemErrors.h:112:53: error: use of undeclared identifier 'ENAMETOOLONG'
        MtpNameTooLong() : MtpFilesystemErrorWithErrorCode(ENAMETOOLONG, "Filename too long") {};

(more detailed output below)

I'm guessing there's some kind of C library I'm missing. I have libmtp, libmagic, and osxfuse installed via brew, and it seems to be finding those libraries without trouble. I thought it might be my version of gcc, so I installed brew's version and set environment variables to point to those binaries and re-ran configure and make, and it looks like it picked up those differences, but the errors happened again anyway..

Any idea what I'm missing / doing wrong?

I have googled the errors, and the constants themselves, but wasn't able to find anything leading me in the right direction..

I am also having this same issue.

I tried including errorno.h and this solved the problem of the constants being undefined, but this only had other issues

[sebastianhaberey]

"The undefined errors are simply part of the <sys/errno> headers and the headers so simply add:

#include <sys/errno.h> 
#include <string>

to src/mtpFilesystemErrors.h."
